Polyaluminum chloride (PAC) – the birth of a highly efficient inorganic polymeric flocculant. The molecular structure of PAC determines its unique technical performance in water treatment processes.

From turbid to clear

During industrial wastewater treatment, the water body exhibits turbidity, high levels of suspended solids, and high color intensity. Traditional treatment methods have limited efficiency, slow sedimentation rates, and difficult-to-control operating costs. Upon the addition of PAC (polyaluminum chloride), it rapidly hydrolyzes, and these active substances act like "bridges," quickly connecting, adsorbing, and bridging the tiny suspended particles. The previously dispersed impurities begin to aggregate, enlarge, and settle.

High processing efficiency

In the industry, PAC (polyaluminum chloride) is present in almost every key water treatment process:

Industrial wastewater treatment: Widely used in the paper, textile dyeing, and chemical industries.

Municipal wastewater treatment: improving sedimentation speed and reducing operating costs.

Sludge dewatering pretreatment: Improving sludge cake properties and increasing dewatering efficiency.

PAC has advantages such as low dosage, wide applicability to different water qualities, and fast sedimentation speed. These characteristics have made it gradually become a standard product in the global water treatment industry.

Conclusion

From municipal water plants that supply drinking water to millions of people, to industrial recycling systems that optimize resource utilization; from environmental engineering projects that reduce sludge volume, to the production of ultrapure water that supports precision manufacturing – polyaluminum chloride, with its efficient, stable, and controllable properties, consistently supports every critical aspect of modern water treatment technology.
